Correct Answer: B

Rationale: Critical pathways are designed to outline the expected sequence and timing of interventions to achieve optimal patient outcomes for a specific medical condition. Components such as the expected length of stay, patient outcomes, and medical diagnosis are crucial in developing a critical pathway for congestive heart failure. However, the assigned staff healthcare provider is not typically a fixed component of a critical pathway as it may vary based on staffing schedules and rotations. Therefore, the assigned staff healthcare provider is the component that does not apply.

Correct Answer: D

Rationale: The correct answer is D: 'Two days.' It is preferable to give two days' notice for a performance appraisal. Giving only one day's notice (Choice A) might not provide sufficient time for the employee to prepare adequately for the appraisal. Choice B, 'None,' is incorrect because it is essential to give advance notice for an appraisal to allow the employee time to get ready. Choice C, 'One week,' is too long of a notice period for a standard performance appraisal and could lead to unnecessary delays.

Correct Answer: D

Rationale: The correct answer is D. In functional structures, employees are grouped in departments by specialty, with similar tasks being performed by the same group. This means that in a healthcare system with a functional structure, all nursing tasks would fall under the nursing service. Choices A, B, and C are incorrect because open communication between departments, one department having authority over another, or the level of authority of a particular department do not necessarily represent a functional structure.

Correct Answer: A

Rationale: This is an example of the ethical principle of autonomy.

Correct Answer: B

Rationale: A nurse navigator's primary role is to coordinate complex care for patients, guiding them through the healthcare system. Choice A is incorrect because nurse navigators do not provide direct patient care like nurses in clinical settings. Choice C is incorrect as nurse navigators focus on patient care coordination rather than administrative tasks. Choice D is incorrect as managing clinical trials is typically not within the scope of a nurse navigator's responsibilities.
